In fact, the best lithium ion jump starter can help you jump start your dead car battery all year round as they can still maintain their charge even in winter. Moreover, these devices are portable in most cases, as they usually have very modest dimensions and their weight ranges from 1.5 to 5 pounds. I have prepared 7 detailed lithium jump starter reviews featuring the most attractive options offered in the market today in order to help you find a reliable and long-lasting item.
Lithium Ion Jump Starters Reviews
After testing this 18000 mAh portable car jump starter, I am really impressed with the power of this battery booster enclosed in such a compact cabinet (7.3 x 1.6 x 3.5 inches). Just imagine, this model has the capability to start vehicles with up to 6.5 L gas engine or 5.4 L diesel engine up to 20 times per charge having 600 amps of peak current. Being very compact lithium battery jump starter, the DBPOWER 600A can be easily stored in your glovebox.
Moreover, I was pretty satisfied with the fact that this model provides a smart charging port (the 600A goes with 8 in 1 laptop adapters in the package), which ensures speedy charging of different gadgets, such as your laptops or smartphones. I also like that this battery charger goes with an LCD screen to inform you about the output voltage and the remaining power. However, I was disappointed with the fact that start cables may get melted easily in case of the jump starter has not been cooled down for at least 30 seconds after each use.
- The model is very cheap, though it can be used equally good for different purposes.
- This is a lightweight option (only 2.82 pounds), which means that you can take it almost everywhere.
- It also goes with a built-in compass to help you not to get lost in case of emergency.
- The model warms up very quickly, which increases the risk of getting burnt.
I would like to say that this ultra-safe lithium ion battery jump starter is rated at 1,000 amps and can easily deliver up to 20 jump starts on a single charge. For the reason that the model has reverse polarity protection and spark-proof technology, it can be connected to different batteries safely. Additionally, the GB40 has a capability to jump start up to 3 L diesel engines and 6 L gasoline engines. While having a USB port, the NOCO Boost Plus GB40 can help you recharge your smartphones and laptops. Reversely, you can also recharge this 12V jump starter from any powered USB port. I find it also important to mention that this item uses Joules but not peak amps to start vehicles. This derives from the fact that most vehicles jump starts in 2-3 seconds, so peak amps are not so important here.
However, I am a bit dissatisfied with the length of the charging cables as the manufacturers could have made them longer in order to make the charging process more comfortable. At the same time, I like its compact design a lot (dimensions – 3.2 x 1.7 x 6.7 inches) and the fact that the item weighs only 2.4 pounds, so you can easily put the item in the glovebox of your car. I can also recommend you to plug it into 12V cigarette light in order to recharge while driving in order to have it always ready at hand.
- The model goes with an integrated LED flashlight with 7 different light modes (high, medium, low, flashing, strobe and emergency SOS).
- This multifunctional item is pretty cheap.
- The model is equally good for gasoline cars and electric cars.
- This jump starter does not always work well when it is necessary to jump start trucks.
After working with this item, I would like to say that the JX12 is a very powerful lithium-ion jump starter that is rated at 1200A peak current and provides up to 30 jump starts per charge. This technical characteristic allows this unit to easily jump start 12V vehicles with up to 6.0 L diesel engines and 8.0 L gas engines. Moreover, the model impressed me with its safety features, as it provides 9 intelligent safety functions called to guarantee the safety of the user as well as protect the jump starter from damage. These safety functions include such valuable options as over-temperature protection, short-circuit protection, over-current protection, reverse connection protection, over-voltage protection, and over-charge protection. You are always glad to receive such full-cover protection at such a low price. Moreover, it has pretty compact dimensions (6.9 x 3.5 x 1.3 inches), weighing only 1.2 pounds.
What also makes me leave positive comments is the fact that the JX12 has Type-C IN/OUT port (5V/3A) and dual USB quick charge output ports. Hence, you can use the item for charging your smartphone, laptop, GPS, and other electronic devices way faster than before. However, the jump starter’s cables seem to be rather short compared to those used in similar items in the same price range.
- The model has a very bright built-in flashlight, which can be even used to signal help.
- The item goes with a very durable and solid plastic case, which helps store it better.
- The JX12 can perfectly hold a charge for as long as 6 months.
- The jump starter seems to work very poorly in cold weather.
When analyzing the performance of this particular portable car battery jump starter, I would like to say that it is designed mostly for charging various electronic devices. Surely, this model can also jump start car engines. However, this model is far from being considered powerful as its compact 44Wh lithium ion battery is rated at only 400 amp peak power. This is just enough to jumpstart vehicles with 3 L gasoline engines or 2.5 L diesel engines. The idea of trying to use this item as a jump starter for engines with higher displacement would bring no positive results. In my opinion, this power bank would be useful for those persons who have lots of different electronic devices that need to be recharged from time to time. Buying this item with the purpose to jump start a vehicle would make little sense as this particular item has very modest technical characteristics. Moreover, it will also need to be recharged again just after several jumpstarting attempts.
With so many powerful jumpstarting items in the same price range available in the market today, the Scorpion should not be among the most desired options for car-owners. The item is still a perfect product for everyday charging of various electronic devices (e.g. laptops, smartphones, and Bluetooth speakers) as it has very compact dimensions (6.2 x 3 x 1 inches) and 2.35 pounds of weight.
- The item is easy in use and can be even carried in a pocket.
- The Scorpion holds a full charge pretty well as for such a tiny device.
- Its cables are of very high quality.
- It may jumpstart your engine pretty slowly (1-3 minutes).
Well, this item has so much power inside to easily jumpstart all passenger vehicles and light commercial cars. Its battery size is 22 Ah, which is a very decent result for such a cheap offering. The device is rated at 1,700 peak amps (425 cranking amps), so you will unlikely face any problems with charging a dead battery in your car. Furthermore, I want to emphasize that the item has very reliable copper-insulated cables. Their length is 46 inches, so the process of jumpstarting becomes much more comfortable as you have enough space to connect the cables.
In fact, the Jump-N-Carry JNC660 has been designed exactly with the purpose to jumpstart your vehicles at any weather. While so many items have some issues with jumpstarting at cold weather, the Jump-N-Carry JNC660 can help give the second life to your dead battery even in winter. I also want to mention that the model goes with the built-in charger in order to deliver a longer service life. However, I find it really disappointing that the item can be used for jumpstarting cars solely as it has no LED light and USB ports. Additionally, you should better recharge the battery every month in order to prolong the life of the unit.
- The item can hold the full charge for long.
- The model is stuffed with a reliable voltmeter, which is meant to show the charge status of the battery.
- The item is very heavy (18 pounds) and very bulky (16.3 x 14.1 x 5.1 inches), which makes it difficult to keep it always at hand.
This is another powerful model, which has a 20 amp (10 amps per bank) onboard battery charger that is capable of maintaining two different 12-volt batteries at the same time. What I really like in this item is that it can freely charge all types of lead-acid batteries (e.g. gel, wet, deep-cycle, and AGM batteries) up to 230Ah. On the one hand, the Genius GEN2 is built pretty well, as the model has waterproof and rugged construction. On the other hand, the model is very heavy weighing sensational 9.13 pounds with pretty modest dimensions (7 x 6 x 2.5 inches). Hence, its design is not the strongest feature of this item.
However, the manufacturers of this product have tried very hard to deliver an extremely safe model. Just imagine that this 2-bank charger boasts spark-proof technology, thermal, reverse polarity, overcharge, protection, as well as ignition protection. All these safety features add more value to the model, especially if you keep in mind that the product is backed by high-quality cables and 5 years of limited warranty.
- Suitable for maintaining all battery sizes.
- It has a smart feature allowing the charger to dynamically allocate current from one bank to the other if necessary.
- Being a deep-cycle marine battery, this item is perfect only for motorboat owners.
After testing this 12V portable jump starter, I would like to say that is mainly designed for high displacement vehicles. The thing is that the G18 can jump start all 12V vehicle batteries. The model is a real beast as it offers 21000mAh and is rated at a peak of 2000 amps. Those persons who consider the item not only as the jump starter for their vehicles but also as a power bank for their electronic gadgets, may be pretty glad to find out that the G18 goes with dual USB output.
I also really appreciate the fact that the product goes with built-in voltmeter, which is intended to show the information about the battery voltage. Moreover, the product also boasts the spark-proof technology that is meant to prevent short circuit and ensure safe operation. Additionally, the G18 is a very compact battery charger (7.6 x 3.5 x 1.5 inches) weighing as less as 1.47 pounds. The design of the item allows users to carry it on a regular basis. However, I do not like the quality of its cables as they may get warm rather quickly during jumpstarting sessions.
- The product goes with rather long cables.
- The item is very cheap.
- The model also supports 3rd Generation QDSP technology.
- The connectors may start falling apart soon if you jump start your car very often.
Tips on Choosing the Best Lithium Ion Jump Starter
The main thing you should keep in mind before searching for a new jump starter is to look at how many amps your vehicle needs to start a car. At this point, it is also significant to mention that jump starters can provide cranking or peak amps. Peak amps are the value that refers to the highest current that your jump starter can push out when jumpstarting your engine. At the same time, the cranking current is the value that describes a more accurate measure of what power your jump starter can really deliver. This means that cranking starts your engine before your item gets out of charge. Moreover, you should also pay attention to the size of jump starter you need to choose to jump start your vehicle. These are the figures you should keep in mind:
- 150-200 A – 4-cylinder gasoline;
- 200-250 A – 6-cylinder gasoline;
- 250-300 A – 8-cylinder gasoline;
- 300-400 a – 4-cylinder diesel;
- 400-500 A – 6-cylinder diesel;
- 600-700 A – 8-cylinder diesel.
Additionally, it is also vital to remember that low temperature may significantly decrease the productivity of jump starters. In most cases, lithium ion batteries lose up to 50% of their cranking current capacity when the temperature drops below zero. Hence, choose those batteries, which can remain effective even in winter.
Short Guide on Using a Lithium Ion Battery
Those who have not used these devices before usually have lots of questions on how to use the items mentioned in our lithium ion jump starter reviews. This often happens with those drivers who have decided to replace their outdated lead acid battery jumpers with the new lithium ion chargers. Compact size is the main reason that pushes people to opt for lithium ion batteries. However, small dimensions usually mean that the item should have less raw power output than its lead acid counterpart. That is why cranking the engine immediately with a lithium ion charger should not be a key to jump starting your engine. Instead, you should follow these steps:
- Attach a lithium ion jump starter to the car battery;
- Wait at least 1 minute;
- Try to jump start your engine;
- If nothing has happened yet, wait several minutes more and try to crank your car again.
One thing I want to mention is that most lithium ion batteries have smaller cables than other battery jumpers. Thus, they need 1-3 minutes to deliver the charge to the main car battery and jump start the engine properly.
Main Benefits of Having a Lithium Ion Jump Starter
Obviously, the owners of lithium ion battery chargers enjoy multiple benefits from using these reliable items on a regular basis. First, these products are usually very compact and lightweight, especially when compared to heavy lead acid battery chargers. Second, lithium ion batteries traditionally go with high-end microprocessors, which have a mission to ensure safety and full protection. Third, these items tend to have a lot of cranking amps, which guarantee that the user will use it multiple times before it will lose its charge. Moreover, these devices are multifunctional, so you can also use lithium car jump starter for recharging your electronic devices through built-in USB ports.
